Pressed Steel Swivel Castors with White Nylon Wheel & 4-Hole Top Plate
A pressed steel swivel castor is a heavy-duty mobility fitting engineered to be bolted directly onto the underside of equipment, trolleys, carts, shelving units, and furniture via a four-hole top plate. This range features a durable white nylon wheel available in five diameters — 80 mm, 100 mm, 125 mm, 150 mm, and 200 mm — with individual load capacities from 120 kg up to 230 kg per castor. The full 360-degree swivel action and precision ball journal bearing deliver smooth, low-effort directional control across hard floor surfaces, making these castors a trusted choice for warehousing, manufacturing, retail, hospitality, and workshop environments throughout the UK.

* All five sizes share the same pressed steel body construction, white nylon wheel, ball journal bearing, and 85 Shore A tread hardness. The 80 mm–150 mm variants use a 100 mm x 85 mm top plate; the 200 mm variant uses a larger 141 mm x 115 mm top plate. Hole diameter is 10 mm across all sizes. Number of fixing holes: 4.
80 mm — 120 kg Load Capacity
The 80 mm swivel castor is the most compact option in this range, purpose-built for applications where floor clearance and a minimal footprint are priorities. Despite its smaller profile, it delivers a confident 120 kg per-castor rating — supporting up to 360 kg across a four-castor set — and rolls quietly and smoothly on hard floors thanks to its precision ball journal bearing and 85 Shore A nylon tread. The 106 mm total height suits low-profile frames and furniture bases where ground clearance is limited.
- Office furniture — desks, filing cabinets, and storage pedestals requiring quiet, low-profile mobility
- Retail display units — gondola shelving, display stands, and point-of-sale fixtures on tiled or vinyl floors
- Workshop benches — light-duty workbenches and tool trolleys in garages and small workshops
- Hospitality furniture — service trolleys, bar carts, and catering equipment in hotels and restaurants
- Medical and laboratory — instrument trolleys and equipment stands on smooth clinical flooring

100 mm — 140 kg Load Capacity
Stepping up to 100 mm, this castor offers an enhanced 140 kg per-castor capacity — up to 420 kg across four — while maintaining the same compact 100 mm x 85 mm top plate footprint. The slightly larger wheel diameter improves roll-over performance on minor floor imperfections and reduces push effort on longer runs. At 127 mm total height, it suits most standard equipment frames and is a popular choice for warehouse trolleys, catering equipment, and light industrial carts.
- Warehouse trolleys — picking trolleys and order fulfilment carts on concrete or sealed warehouse floors
- Catering and food service — bain-marie trolleys, plate racks, and kitchen service carts in commercial kitchens
- Light industrial carts — component transport trolleys and parts bins in assembly and production environments
- Retail stockroom equipment — roll cages, stock trolleys, and back-of-house shelving units
- Educational and institutional — AV trolleys, library book carts, and equipment stands in schools and universities

125 mm — 160 kg Load Capacity
The 125 mm castor represents the mid-range sweet spot for general industrial and commercial use. With a 160 kg per-castor rating and a combined capacity of 480 kg for a four-castor set, it handles the demands of assembly line carts, workshop equipment trolleys, and heavy retail fixtures with ease. The wider 37.5 mm tread provides improved stability under load, and the 157 mm total height is well suited to standard-height industrial frames and workbenches.
- Assembly line carts — component and sub-assembly transport in manufacturing and production facilities
- Workshop equipment trolleys — tool chests, welding trolleys, and equipment stands in engineering workshops
- Heavy retail fixtures — gondola shelving, display plinths, and large point-of-sale units in retail environments
- Print and reprographics
paper trolleys, print finishing carts, and large-format equipment stands - Facilities management — janitorial trolleys, cleaning equipment carts, and maintenance supply units

The 150 mm castor steps into heavy-duty territory, rated at 180 kg per castor and up to 540 kg across a four-castor configuration. The larger wheel diameter rolls more easily over uneven surfaces and reduces the effort required to move loaded equipment over longer distances — a key advantage in busy warehouse aisles, hospitality back-of-house areas, and manufacturing floors. The 40 mm tread width adds lateral stability, and the 181 mm total height suits taller trolley and cart frames.
Typical Applications- Warehouse and logistics — heavy picking trolleys, pallet dollies, and goods-in/goods-out carts on warehouse floors
- Hospitality back-of-house — linen trolleys, laundry carts, and bulk catering equipment in hotels and large kitchens
- Manufacturing and production — heavy component trolleys, die carts, and machine base mobility in factory environments
- Healthcare and care homes — linen and supply trolleys, equipment stands, and mobile storage units in clinical settings
- Events and staging — flight case dollies, AV equipment carts, and staging equipment on smooth venue floors

The 200 mm castor is the flagship of this range — engineered for the most demanding load-bearing applications. At 230 kg per castor and a combined maximum of 690 kg across four, it is built for heavy industrial trolleys, large machinery bases, and high-capacity storage equipment. The 50 mm tread width delivers exceptional stability under load, while the larger 141 mm x 115 mm top plate provides a more substantial fixing footprint to match the increased forces at play. At 242 mm total height, this castor is designed for taller, purpose-built frames.
Typical Applications- Heavy industrial trolleys — die trolleys, mould carts, and heavy component transport in steel, automotive, and engineering industries
- Large machinery bases — mobile machine bases, generator sets, and compressor units requiring robust, high-capacity mobility
- High-capacity storage — heavy-duty racking dollies, bulk storage carts, and archive trolleys in distribution centres
- Construction and site use — material handling trolleys, scaffold component carts, and site equipment on smooth concrete surfaces
- Print and packaging — reel trolleys, large-format print equipment bases, and heavy finishing machine mobility

Start by establishing the total weight of your equipment when fully loaded, then divide that figure by the number of castors you intend to fit — typically four. The result is the minimum per-castor load rating required. Always select the next size up to build in a safety margin and account for dynamic forces during movement. As a general rule, larger wheel diameters roll more easily over longer distances and minor floor imperfections, so if your equipment will be moved frequently or over uneven surfaces, opt for the 150 mm or 200 mm option.
Are these castors suitable for use on hard floors such as concrete, tile, or vinyl?
Yes. The white nylon wheel with an 85 Shore A hardness rating is specifically suited to smooth and hard floor surfaces including concrete, ceramic tile, vinyl, epoxy-coated floors, and sealed timber. Nylon wheels roll efficiently on these surfaces with minimal resistance and do not leave marks or deposits. They are not recommended for use on soft, carpeted, or heavily textured surfaces — for those environments, a softer rubber or polyurethane wheel would be more appropriate.
How do I fit a 4-hole top plate castor to my equipment?
Top plate castors are secured using four bolts through the pre-drilled holes in the mounting plate. For the 80 mm–150 mm variants, the plate measures 100 mm x 85 mm with hole centres of 80 mm x 60 mm and a hole diameter of 10 mm — M10 fixings are appropriate. The 200 mm variant uses a larger 141 mm x 115 mm plate with hole centres of 105 mm x 80 mm. Mark and drill corresponding holes in your equipment frame, then secure with M10 bolts, washers, and locking nuts. Always ensure the fixing surface is flat, structurally sound, and free from debris before installation.
Can I mix different castor sizes on the same piece of equipment?
It is not recommended to mix castor sizes on the same unit. Differing total heights will cause the equipment to sit unevenly, placing unequal stress on individual castors and potentially exceeding their rated load capacity on the lower-set units. For best performance and safety, always fit four castors of the same size and specification. If you require a specific height that falls between two standard sizes, please contact us to discuss your requirements before ordering.
